Magnetic Particle Testing(MT)
During Magnetic Particle Testing, a magnetic field is introduced to the material being tested, which causes any magnetic particles to align themselves with the lines of force created by the magnetic field. When a magnetic particle is introduced to a surface and sub-surface flaw or impurity, it will be attracted to the site of the flaw, creating an easily visible indication that the flaw has been detected. This method is quick, efficient, and non-intrusive, making it a preferred testing method for many industries.
